VAPOR-BURNERJ SPECIFICAIIOZ. forming part of Letters Patent N0. 493,079,dated March '7, 1893.

Application filed July 15, 1892. Serial No. 440,15'7. (No model.)

To aZZ whom it may concern.-

Be it known that I, ANTOINE GATEAU, a citizen of the Republic of France,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use ful Improvementsin Vapor-Burners, of whichthe following is a specification.

Considered in its general aspect, the object of the present invention isto improve vapor burners, and especially vapor burners of the classshown and described'in Letters-Patent No. 435,693, which were granted tome on the 2d day of September, 1892, and the particular features ofnovelty in which the invention resides, are particularly pointed out inthe claims, being first fully described with reference to theaccompanying drawings, which are made a parthereof, and in which,

Figure 1, is a vertical section of a'vapor burner embodying theinvention. Fig. 2, is a side elevation thereof. Fig. 3, is a plan viewof the oil cup. Fig. 4, is a horizontal section of the burner on theline C-D, the parts below the cutting plane being shown in plan.

The part of the burner which sustains all of the other parts, consistsof a single casting, comprising an annular cup 1, a ring 3 concentrictherewith, two or more struts located between them and extending fromone to the other, and the shell or casing of a valve 7. The side wallsof the cup consist of concentric rings, or short tubes, and the innerone of these is continued downward below the bottom of the cup, as shownat A. The interior surface of the outer wall of the cup is formed withan offset, thus making the cup of two diameters, with the greater attop. Within the portion of smaller diameter, is fitted a ring 6 ofperforated sheet metal, and within this ring is a similar ring 6' ofsmaller diameter, a wick 5 of asbestus or similar material beingarranged in the annular space between them. The object in forming thecup of two diameters, is to provide means for holding these wick tubes6, 6' in place and at the same time leave between the outer one and thewall of the cup, an annular space into which air can enter.

2 and 4 are two perforated tubes united at top and held concentric witheach other by means of a number of struts interposed between them at alower level. The former of two tubes may be elevated high enough toafford access to the cup for charging it with gasoline or similar oilfor starting the burner.

While the burner may be started in this way, still I do not prefer it. Iprefer to start it by placing a lighted lamp beneath it and allowing theheat escaping therefrom to pass up through the burner, as shown in thepatent above referred to. In order to regulate the admission of air tothe lower part of the burner, I secure to the-ring 3 a perforated cap 9,which is closed at bottom save for a central opening, and I provide adoor 10 pivoted at 11, whereby this opening may be closed when desired.

8 is a casing secured to the outside of the cup and to the bottom of thetubular extension A for the purpose of preventing loss of heat byradiation.

The central perforated air tube, 2, has its lower end slipped into thecentral opening of the cup 1 and carries at its upper end the spreader16. As customarily constructed this tube discharges all of its air belowthe spreader, so that the air comes in contact with the flame before theflame comes in contact with the spreader. With this arrangement, theflame has a tendency to hug the spreader and curl inward over the top ofit. According to my invention, I provide the spreader with an openingthrough which air from the central air tube may pass above it and Iplace opposite this opening a deflector 13 for throwing the air outwardagainst the interior of the annular flame, as it passes upward aroundthe spreader. As shown in the. drawings, the spreader is provided withone large central opening (reducing it to the form of a ring) into whichthe upper end of the central air tube fit s,and the deflector 13consists of a disk held a short distance above the top of the spreaderby means of a suitable number of struts or posts 17. Rising from the topof the spreader, just beneath the periphery of the deflector, is anannular flange which terminates a short distance from the under side ofthe deflector, leaving a narrow opening or slot 18, through which theair escapes.

Secured to the central tube 2 and held concentric therewith by asuitable number of struts, is a short perforated tube 12, which extendsdownward to about the top of the oil cup.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. In a vapor burner, the combination with the annular vaporizing cup 1having a central opening for the admission of air, of the centralperforated tube 2 fitting upon the inner wall of said cup, an annularspreader secured to the upper end of said tube, a deflector situatedopposite the open end of said tube and above the spreader, theperforated tube 12 surrounding the tube 2,the perforated tube 2surrounding the tube 12 and fitting upon the outer wall of the annularcup,'the nonperforated tube 4 surrounding the tube 2, the upper ends ofsaid tubes 4 and 2 being secured together, the annular ring 3, uponwhich the tube 4 rests, radial braces connecting the ring 3 and annularcup, and the perforated tube 9 secured to the underside of the ring 3,substantially as set forth.

2. The combination with a Vapor burner, ot' the perforated cap 9 fittedover the bottom thereof, the bottom of said cap being provided with acentral opening, and a closure 10 pivoted to the bottom of the cap andadapted to close said opening,substantially as set forth.
